A manufacturing plan needs to have a horn sound to signal quitting time.The horn sould be activated when either of the following conditions is met :
1. it's after 5 o'clock and all machines are shut down
2. it's Friday . the production run for the day is complete, and all machines are shut down
design a logic circuit that will control the horn . ( Hint: use variabfor logic input variables to represent the various conditions ; for example input A will be high only when the time of day is 5 o'clock or later).
solution :
1. it's after 5 o'clock and all machines are shut down
